CARD Application led September T0 all whom z' may concern.'

' Be it known that I, Grenen H. PEGRAM, a citizen of the United States, residing atV South Grange, in the county of Essex, State of N ew Jersey, have made a certain new and useful Invention in a Card Index, of which the following is a specification.

This invention relates to a card index system in the form of a continuous spiral, and has for its object the provisionof an expansible and continuous .spiral index wherein certain sectionsor card areas are designated for particular records and ready references. v

It is a further object of my invention to provide a continuous `rotatable card index which will admit of the removal or insertion of any card, or number of cards, in the spiral, and wherein the cards are .so shaped and cut as to admit of ready mounting and quick assembling for additional cards. I also mount the spiral index ina suitable supporty and provide means for rotating the spiral so as to bring the different areas into view.l f

Other objects will appear hereinafter, andV I attain these objects by the structure illustrated in the accompanying drawing, wherein- A f Fig. l is a plan View of a construction embracing the principles of my invention.`

clip employed to unite the respective edges of adjacent cards.

Fig. 10 yis a' view taken on lines 10-10 of Fig. 9; and

Fig. 1l is a plan view of a unitcard.

Like numerals refer to similar parts throughout the several views.

It is a prime object of my invention to produce a ready reference in the form of a continuous .spiral and which spiral may be composed of circular, or otherwise shaped, cards radially slit and having the respective edges connected t0 corresponding edges of adjacent cards on opposite sides, thereby connecting any number of cards into a continuous spiral. This spiral card index may be mounted in any con- H venient manner to be rotated in order to bring each card, or reference area, into view. Thus, any number ofv cards may be built up, as needed, and any suitable means may be employed for rotating the spiral, which is supported in any desired or suitable manner. The cards may be circular in shape, but this is not essential, as they may be square or other polygonal shape, as may be desired. Any suitable means may be employed for uniting the slit edges of adjacent cards to thereby form a continuous' or spiral card index.

' The unit of my spiral card system is a card 20, preferably circular, and having a central opening 2l for receiving a supporting or operating journal 31, which journal is supported in a container 32 by bearings 83. The journal and card opening may be square, as shown, or they may be otherwise From the card opening 2l there extends a radial slit 22, and on either side .of the slit a unitingv slot 23 may vbeprovided vfor receiving the ends 24 of the holding clips 25. As is best shown in Fig. 6, yone edge 26 of slit 22 in card. (20) is united to its adjacent card edge 27 of card 20 by/l Yor several cards may be groupedfor a commonv index letter, as conditions may require or 'necessity dictate, and as 1s clearly 1nldicated by Fig. t is aise possible to re move any card bv opening the holding clips, and it additional space is requird any number ot cards may be added at any point in the spiral by simply opening a clip inserting the additional card and Closing the respective holding clips.

ln removing unitiieniber ot the spiral, alter the holdin;V clins are removed which attach the ends ot the unit men bei' to the proximate ends ot' adjat ent unit niembers, the unit member to be moved is then tvvisted laterally to enable the same to be removed Yfrom support 2l, or else the support il is withdrawn troni the spiral. This permits the detached unit member to be removed or replaced bv one or more nevv units; yl`he support '21, it it has been vfithdrawn` is then again inserted through the central openings in the spiral units and the device is again ready i'oiuse.

lt yvill be obse ved that .vhen the card is radially slit, as indicated by fig. li tor example, and these cards are tl ien united iu the manner described almve. the holding clips vi'ill then all be in a eonunon r;I ial plane. To radialh7 distribute` the clips and points et union ot the 'ards l remove a sector from one or more cards. as illustrated 'for example by Fig. '7. ln sinne instances l may diametrieally opposite, as illustrated in Fig. (3, and Figs. T and 8 illustrate the practice ivhere a sector list, lor example,hasbeen removed. I employrv the above methods for radial distribution of the clips and unions to better balance the spiral and to prevent; thickened area due to the position of the clips.

The spiral may be mounted to rotate in a suitable support or container 32, which may be provided with hinged covers 3*. A spacer bar is supplied to separate the ards tor ready consultation. rl`his bar is movably held on rod 36 which rod is held by brackets SG. The other end ot the spacer bar rests freely on bar 37 which bar is held in brackets il?. These bri eliets are t'astenet on to the opposite walls of the container as is clearly shown in Figs; 'l and 2. Any suitable operating means, as a 1ranlc handle SS, may be used to rotate the spiral to thereby cause the spacer bar to expose ditlerent cai-l areas to viev. The data may be written or printed directly ou the. cards or it may be vvritten or printed on paper which is pasted on the cards at the proper areas. For convenience, the cards may be. laid oli' int-o suitable areas by segmental lines 39 or lf), as is bestv shown in Figs. Z and The spaces thus 4.toi-med are availal'ile tor permanent records and are readily brought in vievv by aid ot the spacer bar. The index 'let-ters are preferably placed at. the intersection ot the segmental lines on 'the `'fards and indicate the index oard.

insert halt a card to tiringthe clips The container or cabinet may be pi ovided with a bottom Ishield tl, whirl: may von torni to the shape oll the spiral cards. and a lofh' l2 may oe provided to tasten the rovers. rl`o facilitate the removal olf the spiral index for additional cards or data, l provide the 'abinetwith slots lf3 yvliieh are provide-'l with bearings il; in which the index s`v t xin can be rotated.

vln place ol the laterally plaeed clips L, 2.3', ete., l may use edge clips i t. 'these are, placedl over the edges ot adjacent cards, in the manner shown by 9 and lll, and caused to bite into the cards to thu: unite the edges ot adjacent cards, and thereby forming' a mntinuous spiral as in the ease, vilicn they i'ormer clips are used.

rl`he use or operation oll my ,-ontinuous spiral card system is readily understimd and is very simple, but highly etlieienl. lYith the cabinet open and the. spacer bar approxh mately in position to separate the wirds. it is only necessary to give a ten' turns to the handle. to bring the proper card into vieu'. lt is then held in vie as long as the bar, or spiral, is permitted to remain stationary. Vvvhen the spiral is rotated the bar slides along' the brackets and permits the various cards or card sections to be brought quickly into view.

Vhile I have described a specilic embodiment ot my invention, I do not thereby desire to be understood as having thus limited myself unduly, as various modifications falling Wholly ivithin the scope and spirit ot my invention will no doubt present themselves to those versed in the art.
